THREAD-CUTTING DEVICE FOR THIMBLES.

Application led April S,

This invention has relation to thimbles and has in contemplation moreespecially a thread-cutting device forming `an integral part of thethimble which can be used when the said thimble4 is `on the finger andwhich Y is so contrived that it guardedfor protected against catching orcausing damage accidentally to the user or wearer or to the workpiecewhich is being sewn.

My present invention has for its object the production of a si mpic andcheaply coustructed thread-cutting` device for thimbles possessingadvantages in point of efficiency and durability in that the cuttingdevice is circular thereby enabling the thread to be out from any sideof the thimble; further the said cutting device is located at the top ofthe thimble andis protected by suitable guards located around the upperperiphery of the thimble.

According to this invention the thimble is provided with or has securedto it, at the upper or forward end of the body part ory at orapproximately at the junction ofthe body. and the dome or end, acircular cutting device, the edgeof which projects beyond or outwardlyfrom the body and a series of dove-tailed or similar fingers or guardswhich embrace or project beyond the cutting edge, and are spaced apartat suitabley intervals to expose suiiicient portions or segments of thecutter to cut a thread but to prevent also the cutting edge from cuttingthe work piece or the user. n

The cutting device may be formed in one with the thimble if the latteris made of a suitable metal or it may be a separate ring or disc securedto the thimble in any appropriate manner. y

'The dovetailed or similar guard fingersv may be formed in one witheither the body or the dome of the thimble or-both or they may becarried on a separate ring or band.

With the above mentioned objects in view, the invention consists in thenovel construction of a thread-cutting device for thimbles used insewing and combination of parts hereinafter described, illustrated inthe accompanying drawings, and specified in the claims hereto appended;it being understood that various changes in the form, proportion, sizes,and other minor details of construction withinv the scope of the claimsmay kbe resorted to without de- 1927. serial No. 182,012. f

parting from the spirit or sacrificing any of the advantages of' theinvention.

To more fully comprehend the invention reference is directed to theaccompanying drawings forming a part hereof and of which Fig. l is anelevation illustrating a thimble provided with the thread-cuttingdevice.

Fig. 2 isa plan view of' Figure 1 Fig. 3 is a sectional elevation ofFigure l.

Fig. i is a sectional elevation of a modified arrangement ofthread-cutting device;

Figs. 5, 6, yand 7 are fragmentary plan views showing the dovetailed orother shaped guards for the cutting device.

Referring more particularly 'to the sev-y eral views oif the drawings,wherein like reference letters designate corresponding parts throughoutthe several views, A is the cutting device, B the dovetailed guardlingers, C the body of the thimble land l) Vthe top or dome.

Referring to the embodiment of the .invention shown in Fig. l thecutting device A is formed in one with the body of the thimble. Y

This arrangement is suitable when the body of the thimble is madeofstecl or some other metal which can be sharpened to pre- Vide Tanefficient cutting edge.

In this example the upper end i of the thimble body C Ais bent overtopi-eject outf wardly and is sharpened to provide or con-y stitute thecutting device A. The dovetailed or similar guard fingers or protectorsB are formed on the dome or top D. These fingers are spaced apart aroundthe outer periphery of the top or dome as shown in ure 2. They projectover the cutting device B and are bent over as shown. They thus serve toprovide openings between them to guide the thread topbe out, to`preventthe possibility of contact of the cutting Vedge with the handr of theuser or with the work and at the same time serve to secure the top ordome D of they thimble to the body part C. The top lor dome of thethimble may be secured, however, to the body by other means, and thefingers B may only serve to prevent accidental contact with the cuttingdevice. Conversely the cutting device A may be formed in. one with thetop or dome D and the guard fingers B may be formed on the body part Cofthe thimble.

Referring now to the arrangement shovvn in Fig. l the cutting device Ain this eX- ample,'is made separate from the thimble and comprises adisc'ring or it may be a ring of steel or other appropriate metal, whichis placed on theupper end of the thimble body C. This disc or ring A isot' slightly larger' diameter than the end of the thimble body so thatit projects beyond the thimble Walls. This disc or ring A may be securedto the thimble body by soldering or the like7 or it may be secured inposition by the dovetailed or similar guard vfingers B. The guardfingers B are7 in the present case formed in one with the top or dome D.The dome or'top D may be secured to the ring or disc A by anyappropriate means or it may be secured as shown by providing a rim orflange 'Cl on the upper end of the thimble body C and bending the endsof the lingers B over to embrace the cutting device A and to pass underthe flange or rim G1.

As a modification the dovetailed or similarly shaped guard lingers B maybe formed in part on the body (l and in part on 'the top 0r dolne D inwhich case the lingers B on the body C would be placed alternately withthe lingers on the top or dome D.

The guard fingers VB in place oi being formed on the body C or on thetop oi dome D may be formed on a ring or band which may be secured tothe thiinble body in any appropriate manner.

In Figure 5 a guard B for the lingers from the thread cutting edge A isshown which is of'dovetailed formation or having that coniiguration andit Will be seen in the figin'e in question that the outer edges of thisguard. are'closer together and that the taper inner faces are adapted toretain the thread against the edge of the cutting device.

Although the above mentioned dovetailed shaped guard is the preferredarrangement it will be understood that a guard formed as shovvn inFigures 6 and 7 may be employed to enable a ready insertion of thethread.

This invention may be embodied also in Vopen ended or tailors thimblesin which case the cutting device A is conveniently in the form of a ringWhich may be made in one with or may be secured to the body of thethimble in any appropriate manner. In this case also the guard lingers BVmay be carried on a separate band or ring or if the cutting ring A isseparate from the thimble7 the fingers E may be formed on the thimble.

In use any one of the exposed portions or sections o'l' the blade ispressed against the thread to be cut by a movement of the linger onwhich the thimble is carried.

Having now described my invention What I claim as new, and desire tosecure'by Letters Patent is l. A thimble having a tubular body por tion7and a top plate covering one end of the body portion, one of the saidparts being provided at its periphery With a Yseries ot' tingers .spacedapart and projecting laterally around thc body portion of the thiinble,and a thread-cutting device having a sharp edge which projects laterallyof the smaller end of the body portion of the thimble within the spacesformed between the said fingers.

A thimble having a tubular body portion, and a top plate covering oneend of the body portion7 one et the said parts Ybeing provided at itsperiphery with a series o't' lingers spaced apart and projectinglaterally around the body portion of the thimbie, and;

a thread-cutting disk secured Vvbetween ,the body portion. and top plateand having va sharp edge which projects .laterally of `the smaller endot the body portion Within the spaces between the said lingers. f

In Witness whereof I aliiX my signature.
